Dumbbell Jefferson Curl

Muscles worked

Setup

1. Stand on a sturdy step or plyo box with your feet hip-width apart and toes near the edge.
2. Hold a dumbbell with both hands using an overhand grip, letting it hang naturally at arm's length.
3. Stand tall with your shoulders back and a very slight, soft bend in your knees.

How to do it

1. Begin the movement by tucking your chin to your chest and slowly rounding your upper back.
2. Exhale as you continue to 'peel' your spine down one vertebra at a time, keeping the dumbbell close to your legs.
3. Lower the weight as far as your flexibility allows, ideally reaching below the level of your feet.
4. Inhale as you slowly reverse the movement, rolling back up by stacking your vertebrae from the bottom up until you return to a neutral standing position.

Form checklist

• Move slowly and segmentally; do not rush the descent or ascent.
• Keep your legs straight but avoid locking out the knees aggressively.
• Keep the weight centered and close to your shins throughout the movement.
• Stop immediately if you feel any sharp pain or excessive pressure in the lower back.

Pro tips

• Visualize your spine as a bicycle chain being laid down and picked up link by link.
• Focus on the 'active' stretch in the hamstrings at the bottom of the movement to maximize eccentric loading.
• Start with a very light weight to master the articulation before progressing to heavier loads.

Make it harder

• Increase the weight of the dumbbell while maintaining a slow 4-6 second tempo.
• Use a higher platform to allow for a deeper range of motion if your flexibility permits.
